| Abstract: | Based on the nonextensive Tsallis statistics theory, the generalized Bose-Einstein distribution function is derived. The thermodynamics of a rotating generalized Bose system in the three- and two-dimensional harmonic raps are respectively studied by using it. The influences of nonextensive parameter and rotation frequency are discussed based on the analytical expressions of the particle number, the Bose-Einstein condensation (BEC) critical the ground state condensation fraction and specific heat etc. |

| Keywords: | rotating generalized Bose gas nonextensive parameter Bose-Einstein condensation |
